DIY Pool Care: Reasons Your Pool Might Still Be Green, Even After Adding Chlorine

Proper pool maintenance is important, but when you’re new to DIY pool care, you might make a few missteps. One of the most common issues pool owners experience is when their pool turns green. Sometimes even chlorine won’t fix the problem. It’s not safe to swim in a pool filled with algae, as it can cause skin irritation and bacterial infections.

Algae growth can occur when your pool water chemistry is out of balance or if there are issues with the filtration system. When you notice green pool water, address it immediately—or at least before anyone swims in the pool again.

Here are some pool care tips to help you solve the issue:

  • Prepare the pool: Algae can form when the pool water chemistry is off and there are too many metal elements in the water. Remove everything from the pool, and skim the surface with a skimmer to get rid of leaves and debris. Let any dirt settle to the bottom.
  • Test the water: Next test your pool water. This will tell you what (if anything) to add to the water. For example, if your pool water is cloudy, the pH is on the alkaline side. You’ll need to add hydrochloric acid to the water to neutralize it. You want the pH levels to be around 7, even in a saltwater pool.
  • Shock the pool: Next shock the pool by adding liquid chlorine, according to package directions. Distribute the chlorine around the pool as evenly as possible; then turn on the filter. Let it circulate several hours before you start cleaning the pool. You may want to use an algaecide for best results. Then you can brush the pool to get rid of the algae and other debris.
  • Pump and filter the water: If your pool water is still green after following the steps above, there may be a problem with the filter. Check the filter to make sure there are no clogs; then let it run for several days until the water turns clear once more. If you want to filter the water in a hurry, backwash the filter four times.
  • Make sure you have the right filter: Finally, if all else fails, check your filter to see if it needs to be replaced. If you have a sand filter, check and backwash the filter each day until the water is clean. For cartridge filters, see if the cartridge needs to be replaced; then run the filter twice per day until the pool is completely clean.

Sometimes pool chemistry can present a challenge. If you’re having trouble balancing its chemistry, call a pool maintenance contractor for help. DIY pool care can save money, but sometimes it’s best to call in the experts. Proper pool maintenance is the key to preserving and enjoying your pool for years to come.
